All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c\) is a smooth curve with one turning point. The turning ...

where a, b, and c are numerical constants and c is not equal to zero. Note that if c were zero, the function would be linear. An advantage of this notation is that it can easily be generalized by ...

Practice how to recognise and determine the equation of a quadratic function from its graph ahead of your National 5 Maths exam with this interactive maths quiz. The equation of a a quadratic function ...

Abstract: The composite quadratic function based on a group of quadratic functions was introduced in our earlier paper. Some important properties of this Lyapunov function were revealed. We showed ...

Most people finish studying mathematics without understanding the beauty of mathematical formulas, but there are some people who can feel that only a few "mathematics are beautiful", and how can we ...

Abstract: This paper develops a quadratic function convex approximation approach to deal with the negative definite problem of the quadratic function induced by stability analysis of linear systems ...
